Scarlet rain fell suddenly, and the world turned into purgatory overnight. The strange rain of blood triggered a global mutation: plants turned into man-eating vines, animals turned into armored monsters, and humans were even more divided - most people turned into bloodthirsty zombies, and only a few people awakened their special powers in desperate situations.
When Lin Chen, an ordinary college student, was surrounded by mutant vines, he took the risk of swallowing unprocessed mutant fruits and awakened the "transformation" power. He could fuse and decompose items to create weapons. He teamed up with his roommate Chen Yu to seek the truth. Chen Yu also awakened the ability to control electronics and became a technological pillar.
The two trekked through the crisis-ridden city, collecting energy fruits to strengthen themselves, and met various survivors along the way: Su Qing, a descendant of a martial arts family, became the main force in the battle with her strong skills, and Li Yue, an intern, used medical knowledge to treat the wounded. But he also encountered the insidious Zhao Kai, whose selfish behavior put everyone in danger many times.
The mutated fruit is both hope and risk. When Zhao Kai was swallowed by a monster, he merged with the energy of the fruit and transformed into a terrifying mutant that attacked his companions. Lin Chen and his partners not only have to fight against monsters, but also deal with the betrayal of their own kind. The truth about the changes in the world behind the Scarlet Rain is gradually revealed in their footsteps.
